After bringing in 32 wood dryers from Tech Drying Co., the wood processing procedures in Bangladeshi client company have changed completely. The time for drying wood has dropped by 70%, which has remarkably improved production efficiency. Also, drying defects like cracking and warping have been cut down significantly.?

Manager Abdul Baten said, “For chapalish?and gamari?woods, which we often use in furniture production, the custom – made drying curves of Tech Drying’s dryers are really important. By carefully controlling the temperature and humidity, we can get the wood’s moisture content to the right level. This has stopped furniture from cracking and warping when being exported. Because of this, the number of high – end orders has gone up by 35%.”

Why Choose Tech Drying’s Wood Dryers?

?Strong Professional Know – how?：Tech Drying has over 25 years of experience in developing wood drying technology. It designs drying plans carefully for the humid climate in Bangladesh and common local woods such as chapalish, gamari, and sundari. With its well – developed technology, it makes sure the drying results are the best.?

?Recognized All Over the World?：Tech Drying has set up more than 3,000 drying kilns in over 45 countries around the world. In Bangladesh, it has helped many timber companies improve their drying processes. The equipment has worked steadily since it was installed.?

?Suited to Local Needs?：Tech Drying knows well about the production scale, wood features, and market needs of Bangladeshi timber companies. The equipment and technical services it offers fit perfectly with the local industry. This helps increase production efficiency and the competitiveness of products.

What Are the Drying Solutions for Common Hardwoods in Bangladesh??

Precise Control of Starting Moisture Content?：Using high accuracy moisture meters, we can measure the starting moisture content of hardwoods like chapalish. It usually ranges from 40% to 60%.?

Custom – designed Drying Curves?： The wood dryers have special drying curves set in advance. These curves cover processes like pre – heating, heating, spraying, and dehumidifying. For example, for chapalish wood, we heat it slowly at 40°C with a humidity of 80% – 85%. When the moisture content goes down to 30%, we raise the temperature to 55°C – 60°C and lower the humidity to 60% – 65%. This makes sure the final moisture content reaches 8% – 12%.?

Improved Air Circulation?： The fans are placed in a proper way. Whether the fans turn forward or backward and at any speed, they keep the same efficiency and air volume. This is very important as it makes sure the hot and humid air spreads evenly around the wood, ensuring the wood dries evenly.

Furniture Company in Brazil transformed its radiata pine drying process by purchasing our high-speed softwood drying kilns. This innovative fast drying technology cuts the drying time to just 1/5 of the original. It significantly reduced wood drying defects and helped secure an order for 800,000 dining chairs. Here’s how it happened.

Company Overview

Established in 2007, the Brazilian furniture manufacturer specializes in solid wood dining tables, chairs, and customized bedroom furniture components. The company operates 3 modern panel furniture lines and 2 solid wood processing lines. It has an annual capacity of 25,000 furniture sets. To maintain high-quality standards, the company has strict requirements for the stability and processability of radiata pine (its main raw material).

Challenges of Traditional Lumber Drying Methods

Previously, drying radiata pine logs took 45 to 60 days. Traditional drying kilns, operating at temperatures below 100°C, couldn’t meet the company’s production demands. Fluctuations in wood moisture content led to a 12% deformation rate in the wood panels, causing annual losses of over $2 million. These outdated methods didn’t meet North American quality standards, and the snail – paced drying held back production.

The Innovation of High Temperature Fast Drying Kilns for Softwood

To solve these problems, we designed high-temperature drying kilns specifically for plantation softwoods like radiata pine. Unlike traditional kilns, these new kilns can reach temperatures up to 120°C, offering major advantages:

Fast Drying

Small – sized radiata pine can be dried within hours, 3 to 5 times faster than traditional drying ovens. This greatly boosts production efficiency.

Improved Wood Quality

High temperatures soften wood components, especially lignin, which binds wood fibers. This kiln features a high-efficiency reversible fan system that continuously alternates airflow direction to eliminate stagnation, ensuring uniform moisture distribution across lumber stacks.?This helps prevent common drying issues like twisting and warping, ensuring the wood stays structurally sound and dimensionally stable.

Customized Kiln Drying System

• 6 X 50m^3 kilns (300 cubic meters in total)
• 100 -120 °C Drying specially desgined for softwood
• PLC intelligent control system with 12 sets of high precision temperature and humidity sensors (accuracy: ±0.5°C/±2% RH).
• Multi-stage drying process, precisely controlled the moisture content of radiata pine, kept between 10% and 12%
• The drying cycle is reduced to 7 – 15 days.

Annual Drying Capacity Increased by 70%

The new drying kilns brought outstanding results.

• Defect Reduction: Internal cracks plummeted from 9% to 1.2%, and panel deformation dropped to 3.2%.
• Energy & Capacity: A 60% cut in energy use and a 70% boost in annual drying capacity (to 75,000m3).
• Business Growth: In 2024, the company’s exports surged 35%, fueled by a landmark 800,000 chair order from the US.

Radiata pine is a cornerstone of forestry in South America, Australia and New Zealand. Tech drying solution addresses common pain points faced by drying softwoods.
